HORSE- POWER.

SPECIFICATION forming part of Letters Patent No. 269,057, dated December12, 1882.

I Application tiled October 20, 1882. (No model.)

To all Qc/Loin it may concern.-

Be it known that l, A. Gr. HOLBROOK, a citizen of the United States,residing at Livermore, in the county of McLean and State of ingdrawings.

Figure l is a top view of my improved horsepower. Fig. 2 is a side view.Fig. 3 is a bottom view, and Fig. 4 is a longitudinal vertical sectionalview.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to horse-powers; and it consists in certainimprovements in the construction ofthe saine which will be hereinafteri'ully described, and particularly pointed out in the claims. f

In the drawings hereto annexed, A represents the frame; B B, the axles,and C the transporting-wheels. Frame A has a central cross-piece, D,provided with a pintle, E, upon which isjournaled the master-wheel F, towhich the sweeps Gr are suitably connected. The masterwheel has teeth orcogs H upon its under side, and is provided with an outward-projectingannular, iiange, I, which is supported upon travelers J, journaled uponbrackets K upon the sides of the frame. Travelers L, bearin g upon theupper side or face of the master-wheel, are also journaled to brackets Mat the ends of the frame. ,A

N is a shaft, journaled in suitable bearings in the rear end of theframe and in a crosspiece, O, of the latter. Said shaft carries at oneend a pinion,P, engaging the master-wheel,

and at the other end a bevel-gear, Q, meshing with a pinion, R, upon ashaft, S, journaled vertically in cross-pieces O and T.. Shaft S carriesat its lower end a large horizontal bandwheel, U. 1

'V V are vertical pulleys, journaled upon studs W, projecting downwardlyfrom the frame, adjoining the band-Wheel U; and X X are horizontalpulleys, mountedupon brackets Y Y, projecting downwardly from the rearend of the frame, adjoining the pulleys V.

Z is a box hinged to the rear end of frame A, so that when not in use itmay be folded up against said frame for transportation. Upon atransverse shaft, A', in said box arejournaled a pair of guide pulleys,B', parallel to the pulleys K.

C' is an inverted trough or box, tapering iu direction of its length,and having transverse shafts D', upon which are journaled pulleys E',arranged in any suitable manner, to guide the driving-belt F', which, bysaid box and by the box Z, is protected from exposure and prevented frombeing entangled.. Just beyond the end of box C the belt F' passes overthe driving-pulley of the machinery to be operated.

The box G' is provided on its under side with cross-pieces G', formingbrackets H', adjoining which stakes may be driven, so as to secure thebox in position during operation. Box C' may also be suitably secured tobox Z.

The operation of my invention will be readily understood.

My improved horse-power is exceedingly simple in construction,containing but four gear-wheels, thus avoiding loss of power byfriction.

The belt by which motion is transmitted is, as will be seen, thoroughlyprotected during operation.

I claim and desire to secure by Letters Patent of the United States- 1.The combination of the frame, the horizontal master-wheel having cogsupon its under side, a horizontal shaft carrying a pinion engaging saidmaster-wheel and a bevel-gear, a vertical shaft carrying a pinionmeshing with said bevel-gear, and a large band-wheel and suitabletravelers supporting and guiding the master-wheel, as set forth.

2. The combination, with a horse-power having a band-wheel, and adriving-belt for transmitting motion, ot' a hinged box havingguidepulleys for said belt, as set forth.

3. The combination, with a horse-power having a band-wheel, and a driving-belt for transmitting motion,.of suitable boxes or inverted troughsadapted tocover and protect said driving-belt, and containing pulleys toguide the same, as set forth.

4. The combination, with the horse power having a band-wheel, and adriving-belt for transmitting` motion, of the hinged box oonmy own Ihave hereto affixed my signature in taining guide-pulleys for said beit,and in loose presence of two witnesses. box, likewise containingguide-pulleys, and provided on its under side with cross pieces, .ALBERTG' HOLBROOK' 5 forming brackets, by which said box may be Vitnesses:

secured in position, for operation as set forth. A. I. MUORE,

In testimony that I ciniln the foregoing as i GEO. RUDY.
